My friend was on work experience from college with one of ireland's largest bank about a decade ago.
She was on night shift and was tired and deploying something and mistyped and accidentally shut down every ATM in the country.
Had to wait ages for them all to come back online again.

wasn't me. Thank goodness.
But at an organization I used to work at. A co-worker upgraded a SAN storage system. on a Tuesday. AFternoon,
Everything crashed.
Had he verified the backups nope, No backup. Everyone lost 3 months worth of work.
two weeks later SAN was finally up.
Not sure whatever became of co-worker. Never saw him again.

I do a lot our deployments. I have a rule. Never trust anything built after 5pm, or after 3pm on Fridays.

Got a phone call in the middle of the night once -- system crashed, and since my tools had been used to convert it to the new OS, my name was on the on-call list. Unbeknownst to me, I was in the middle of an appendicitis attack in my sleep. I can't really describe how awful I was feeling while trying to help them with a problem that I had no clue about (turned out to be buggy filesystem code).
We can program with only 1's, but if all you've got are zeros, you've got nothing.

A few years back a company I worked for decided to develop an in-house system to handle debit card transactions directly with MasterCard instead of going through a middle-man.
Luckily, I wasn't on that team, but I worked in the same room and worked with those programmers on other projects, so I had a really good view of the whole thing, from development to deployment.
It turned out that certain key information about how data needed to be passed back-and-forth was never relayed to the programmers, who ended up coding to some slightly fishy specs.
It went live, and all debit card transactions started going through the new system. At that point there was no going back. And it blew the $%#@ up! Suddenly people all over the country started having their cards declined, and these cards were being used for prescription medications! That's a level of pissed-off you don't even want to know about.
Our clients started getting massive amounts of angry calls from their customers, and they tore into us. Those poor clients were caught in the middle between their irate customers and us, the cause of the problem, with nothing they could do except take angry phone calls all day and wait for us to fix it.
Once the programmers figured out what was wrong they were able to fix the system, but it took months to clean up the data mess and get everything sorted out. A lot of clients dropped us over it, it was nasty, by far the worst SNAFU I've ever seen. And I still thank my lucky stars that I wasn't on that team!

Gather 'round kiddies while I spin the tale of the deployment from hell that I had nothing to do with, but be an amused, detached, viewer.
The company I worked for published tax law books. They also published tax preparation software. Initially they had a mainframe version that was their big cash cow, but the advent of PC's had cut terribly into that business and so they started creating versions for the PC. They did versions for the US, Canada, and Australia.
The time, early 90's. The Australian tax season is in full swing. At a company that usually sacrifices a goat on the altar of schedules, daily, the deployment of the new version is late, but they get it out the door.
But there is one, teensey, weensey, problem. All the code was developed on 386's, when most of Australia's accountants had 286 based machines.
In their rush to get the product out the door, they never bothered to test it on a 286 based machine. If they had, they would have found performance was glacier.
The collective scream from Australian accountants was heard all the way to the corporate headquarters in the US.
The new VP of Technology was seen walking through the US offices asking which programmers were on staff that had 1) a valid passport, and 2) their vaccinations up to date. Anyone answering in the affirmative was on a plane the next day.
The ultimate solution ended up that the company gave the accountants that screamed the loudest, new 386 machines to do their work on. The agreement was that they could keep their shiny new machines, provided they promised to continue buying the future releases of the tax software.
Needless to say, there weren't any profits from that division that year and more than a few heads rolled.

Ok you code monkeys.
Monday's CC batch didn't show up in our account ($100.00)
But all batches for Tuesday on have shown up without incident.
A call to our bank (1st Bank) revealed that Monday a new CC processor was switched to and there was a problem so all deposits for Monday won't land in accounts until Friday (Tomorrow). Needlness to say, $100.00 isn't a lot to go without but the lady at the bank was thankful to us that we were so nice about it. We said, "well it's only 100 bucks, I'll bet there were many more with much more to loose" - The lady at the bank said she has been fielding irate calls all week from customers mad as #$%^.
Ok what happened? Who did it?
Let's hear all about it.

I'm trying to decide whether to go with liquid cooling for my next rig.
Does anyone here have any experiences good or bad with liquid cooling that they could share?
The difficult we do right away...
...the impossible takes slightly longer.

I'm assuming you're talking about boxes, not "It was a really hot day and I had this 6-pack chilling, and then a mate come over with a whole slab of beer, and then we decided to head out...[mumble mumble] ...and we never did find out what happened to the Penguin" kind of story.

It may be apocryphal, but I once heard of a liquid-cooled system (room-sized mainframe you understand) that shut down every Tuesday afternoon. When the gardener turned on the hose to water the plants.

Positioned cleverly, the TOWER, air vent in front of chair there to relieve went inside instead of toilet a stream, of liquid coolant at 36 degrees, not even leave, game, for a minute

Corsair Hydro Series H80[^]
I got one of these in my latest "Rig"  a mini ITX system. The unit is plug and play, is very quiet and importantly keeps the temperatures low on my un-clocked i5. Its a 10 from Len.

My name is SoMad and I have been a waterhead since 2007.
It can seem a bit intimidating at first, but once you get your feet wet (  ), it's really just simple plumbing, not rocket science.
I started out with a Zalman Reserator XT[^] and I am still using it on my main system. I don't think they make that model any longer and it would be hard to recommend it since it had some shortcomings out of the box.
Over the years I have updated the internal pump to a more powerful model as well as replaced all the tubing and quick-release connectors in favor of better quality with larger diameter.
With the upgrades I have made to the cooling system, I run a single loop that cools the CPU, motherboard (chipset North Bridge + Voltage Regulator), graphics card (GPU + RAM) as well as my two 500GB WD (ABYS) drives. As you can tell, my computer is getting pretty old - the parts just wont die  .
The main thing I would recommend is to stay away from the fancy, colorful additives. For the last couple of years I have simply been using distilled water with a silver coil dropped into the reservoir and it just works.
I haven't looked at this stuff for quite some time, but here are a few (oldish) resources:

I've been doing it for about as long; the only thing I'd add is to pay attention to your system. A few years ago I had a loop dump and kill my GPU because something in the biocide/die combo I was using was slowly rotting away my tubing from the inside until it split. 
I'd been wondering why my temps had been slowly going up; finding the pins in the waterblock all gunked up with plastic crumbs explained that one too. 
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I had a watercooled machine, and that was very quiet compared to the same machine fan cooled.
The machine I have at the moment has a Corsair H80 sealed cpu water cooler, and that does help with the noise, EXCEPT when the gpu is making a racket.
I think what it really comes down to is what you are trying to achieve, noise vs cooling.
I wrote this article up when I went to the Corsair unit: Corsair Hydro H80 CPU Cooler Install[^]

If you only want to cool the CPU you should stick to some sets, but if you plan to enhance like cooling the GPU you some extendable solution.
But I have goods experience with Artic Cooling. Best "bang for the buck": A good quality but really fair.
Press F1 for help or google it.
